Description

Impeller Impellers are generally closed because of higher efficiencies and are less prone to wear in the front liner region. Semi-open impellers are more common in smaller pumps, where particle blockage may be a problem, or where the shear provided by an open impeller is an aid to pumping froth.
Another feature of slurry pump impellers is the pump out or expelling vanes on the back and front shrouds. These perform the dual function of reducing pressure (thus inhibiting recirculating flow back to the impeller eye and reducing stuffing box pressure) and keeping solids out of the gaps between the casing and impeller by centrifugal action.
We also accept OEM service, and mine site measuring up, from this we can cut down *0% or more cost of the pump parts resource, and our delivery time is very short, normally *0days is enough for any parts that finalized, for all the normal parts, we have large in stock, so, the standard parts we can supply with *0days: about the quality we can guarantee the same period as the world famous brand.
